Well the expression is not very good English and probably needs a little tweaking. I assume the writer is not a native. ・English has spread to be an international language of late. Would be better Literally is used incorrectly here so I removed it. Permeated is also missunderstood here. I suspect "an" might also be wrong as "the" would make more sense, but that view is up to the writer.

Hello Rina, You can use the verb permeate - English has permeated throughout the world to become an international language. The meaning is very similar to spread but it is more formal. Best wishes Bob
